Remove workaround for MDEV-13941, it served for 5 years,and all affected pre-release 10.2 installation should have been already fixed in between. Apparently Innodb is using is_sparse parameter in os_file_set_size() inconsistently, and it passes is_sparse=false now during first file extension. With MDEV-13941 workaround in place, it would unsparse the file, which is makes compression not to work at all anymore.
